Kalon + Marna = 12/7 hours working together
( I attached two formulas. Use formula 3)
Worker 2 Time = (worker 1 Time) * Total Time / [(worker 1 Time) - Total Time]
Worker 2 Time = ((4) * 12/7) / [4 - 12/7]
Worker 2 Time =

Answer:
lateral area = 180π in²
Step-by-step explanation:
The lateral area is the surface of the cone only.
perimeter of base = 12 x 2 = 24π in
Surface Area = 1/2 perimeter x slant height
SA = 1/2 x 24π x 15 = 180π in²
Answer:
Rs 175
Step-by-step explanation:
Suppose the cost is x and at Rs150 the loss is 150-x (this should be a negative number).
At Rs200, the profit is 200-x.
So we have an equation: minus 150 minus x is equal to 200 minus x.
To solve the equation, the cost price X is Rs175.
